  I would like to point out the following changes:

- New support for 64-bits Linux.
- Changed the KEYPRESS_CB and K_ANY callback are now compatible with 
Portuguese Brazilian ABNT keyboard layout in Windows and Linux.
- Fixed IupDestroy for correct memory deallocation.
- Fixed popup menu bug in Windows.
- Fixed IupTree initialization for LED usage.
- New IupTree feature to rename a node in place.
- New IupColorbar control. It is a palette of colors to allow the selection 
of primary and secondary colors.

Best Regards,
Antonio Scuri
